Ullsperger et al. (2005) used a larger stimulus set in their flanker experiment in order to eliminate this confound; however, they created a different confound.
What are feature repetitions and contingency learning confounds?
This type of t-test is used to determine whether a difference between two means is significant in a within-subjects design
What is a paired t-test?
This step in preprocessing temporally aligns the data from different slices
What is slice timing?
The type of fMRI analysis links different patterns of activity across voxels to different conditions
What is multivariate pattern analysis (MVPA)?
Submitting a paper for a class than you already submitted in another class can be consider this.
What is self-plagiarism?
Activation in which brain region predicts the call volume of advertisements for smoking cessation?
What is the medial prefrontal cortex?
This quantity indexes the degree to which individual sample means vary around the group mean
What is the standard deviation?
This is necessary to interpret the difference between two selective average BOLD responses in rapid-event related designs
What is equating the overlap?
This type of rapid fMRI design allows one to (1) randomize the order of different conditions AND (2) estimate the magnitude of each condition’s BOLD response relative to a low-level baseline
What is a jittered, event-related design?
Botvinick et al. (1999) argue that lower ACC activity on ___ trials than on ___ trials reflects lower conflict.
What are iI trials and cI trials?
What is the most stringent method of correcting for multiple comparisons?
What is the Bonferroni correction?
Name one problem with using selective averaging to analyze fMRI data.
What is 1) unable to correct for or model noise; and what is 2) must equate the overlap?
This type of experimental design can be used to test whether the assumption of pure insertion is violated.
What is factorial design?
According to the Colcombe et al. (2004), exercise had this effect on ACC activity during a flanker task.
What is reduced?
RESELs are the unit analysis for this method of correcting for multiple comparisons
What is Gaussian random field theory?
Researchers use this method of correcting for multiple comparisons is used when they focus on a specific area of the brain
What is region of interest (ROI) analysis?
In this type of fMRI design, it is difficult to estimate the baseline.
What is a rapid, unjittered event-related design?
As the statistical threshold decreases, this type of error increases
What is Type I error?
What type of fMRI design allows one to avoid making the assumption of pure insertion?
What is a parametric design?
If a researcher wants to conduct a fMRI study of the Stroop task, what would be the best design?
What is event-related?
